What if I only have one track and I want to mirror it to the right channel?

Community Answer

Open your sound file. Select the whole thing (Cntr-A). Copy it (Cntr-C). From menu "Tracks", select "Add New" and then "Stereo Track". Paste what you copied into the new stereo track (Cntr-V). On the upper left of the new stereo track pane, select the drop down labeled "Audio Track". From the popup menu select "Swap Stereo Channels". Select everything again (Cntr-A). This should select both tracks. From the "Tracks" menu select "Mix and Render". This gives you a single "stereo" track with identical right and left channels.

Find your mono track; Select the entire thing and Ctrl+C (Copy) it. Click anywhere in the window except the track or any of the menus to deselect your mono track. Ctrl+V (Paste) the new mono track beneath the first one. THEN, click the dropdown with the track's name (directly right of the "X" in the track view window) of the top track and click "Left Channel." Do likewise with the bottom track but click "Right Channel." Make sure you can clearly see both tracks in the window, then zoom in until you can see the samples (small dots on the waveform). Slide one track--either is fine--a few samples to the right or left.
This will give a SLIGHT illusion of being a proper stereo track.
